The LX5503E is a power amplifier
optimized for high-efficiency low-
power applications in the FCC
Unlicensed
National
Infrastructure (U-NII) band, Europe
HyperLAN2, and Japan WLAN in the
4.9-5.85GHz frequency range. The
PA is implemented as a two-stage
monolithic
microwave
circuit (MMIC) with active bias and
input/output pre-matching. The device
is manufactured with an InGaP/GaAs
Heterojunction
Bipolar
(HBT) IC process (MOCVD). It
operates at a single supply of 3.3V
with +26dBm of P1dB, and power
gain of 21dB between 4.9-5.35GHz
and 16dB up to 5.85GHz.
Information

Transistor
For +18dBm OFDM output power
(64QAM, 54Mbps), the PA provides a
very low EVM (Error Vector Mag-
nitude) of 3%, and consumes 150mA
total DC current.
The LX5503E is available in a 16-
pin
3x3mm
2
micro-lead
(MLP). The compact footprint, low
profile, and excellent thermal capability
of the micro-lead package make the
LX5503E
an
ideal
